Maybe you can use a CCD scanner somewhere else. Everything that doesn't look like today's common fancy flat ones has a good chance of being a CCD device. A "scanography" is the first thing I would try here, too. Try different orientations and place the calculator upside down on the scanner. This way you can get a scan where the shadows of the keys are below them, which looks much better than a shadow above the keys as seen in many scanner generated pictures.

BTW, if the software doesn't fit the hardware, make the hardware match the software: keeping an older XP machine for such applications is not the worst idea. Some time ago a friend of mine sold a complete scanning setup (including an old Nikon LS-10 SCSI film scanner*) to a happy new owner. ;-)

*) Yes, there are other ways to get an LS-10 running under a current OS.
